To all whom 'it may concern:

` Be it known that l, DONALD NOBLE, a subject of the King of Great lritain, residing` at Bridgeport, inthe county of Fairlield and State of Connecticut, United States of l America, have invented certain new and useful Improvements in Machines tor Cover;

ving or Insulating lNire 'lilith Yarn or its .appertains to niake and use the same.

My invention relates to certainixnprovements in machines for covering or insulating Wire with yarn or its equivalent, and has for its object to provide means to control the feeding of the `Wire and the proper Winding of Athe covered Wire, and. to prevent the latter from being twisted or broken', particularly during the operation of the covering of the saine.

With these ends in View my invention con-- sists in certain combinations and arrange ments of parts hereinafter fully deseriher and then particularly pointed ,out in the claims which conclude this description.

In the acoolnpanying` drawing Figure l is a plan view of'iny improvement-Fig 2 an elevation of one side of' the machine-Fig. 3 an elevation partly in section of the other side of the niaclune-Fig1 4. a front View. oi the rotary spinning drum `which contains the cop of yarn and the devices for centrolling` the saine during the process of covering the vvirewllig adetail secticaial elevation of the feed disk, and Fig. (3 a detail plan viewof the plate on which the leed disk is supported.

Similar characters of reference denote like parts inthe several ligures oi the drawing,

l'lithcrto. a great deal ot trouble has been experienced with line magnet wil-con ac count oit' breaking1 and twisting (glurinpy the also, in feeding accurately according; to the nurnher of strands ot yarn used and the size of Wire. Fmthcr-- more, machines of this description have, as a rule, been so constructed that a considerable length of the covered wire has between the coveri. l strurnentalities forV .teeoiuaj the 'n-re.

,vcrcome these dilicultics l V c applied an accurate feedingmechanism directly t heel cud of the hellen7 spindle which car an idler, around which the covered Wire is passed, between the spinning nozzle and the feeding disk and have made this idler universally adjustable in order that it may receive and pay olip the covered Wire in, the saine horizontal planes in which the spinning nozzle and feed disk are respectively located, while at the' same time said idler has reference solely to the feeding of the Wira'tlie proper control of the speed of the 'Winding druin and the delivery of the covered Wire from lthe spinning mechanism to the feed dislrpreparatory to the Winding open any suitable spool or reel.

l is the hed or my improvement, 2 a vertically disposed. shaft journaled in any suitable .trarne 3 supported on the bed, l a W -in Wheel, and 5 a pulley both of which carried rloy' said shaft in horizontal position. i

is a platform provided with a series of perforations 7 near its periphery and hava huh 8 which is secured around the upcnd of the shaft by ineens of a, screw t), and l0 is the feed disk which rests upon said platform vwith the hub projectingr loosely through the central` portion of said i', a pin 1l extending loosely through the disk and adapted to he engaged with the perfmations 7 for the purpose presently to he explaiund is a vertical spindle journalcd w'lhin the iii-:aine il and carrying a Worin '13 at its is a lever pivoted at it) to Vthe traine 3 'ryinn a friction roller 20 (shown in Mines) which rests by gravity against the cam 17 so that it will be'clear that as the cam revolves this lever will have a reciprocation in a vertical plane. ,y

21 is an elongated slot in the free end of the lever 1S in which a block 22 isjcapable of moving freely, and 23 is a thumb screw whereby said block may be secured in any suitable adjustment throughout said slot, this manner of arranging the block and providing for its adjustment being a well known and common expedient and requiring nospecilic description. Carried by said block and extending upwardly therefrom through a suitable opening 24 in the frame is a rod 25 whose upper end passes freely through a box 2G and is secured thereto by means of a set screw 27 driven throu h said box against said rod, and extending aterally from this box is a pin 28 lwhich passes loosely through a second box 29.

30 is a vertical post which rises from the frame and loosely inserted in a suitable socket in this post .is a pin 31 whose head 32 normally rests against the post itself. This head is hollow and is open at the top, andl journaled within the sides of this head is a cross pin to which is secured the inner end of the guide rod 34 which latter passes through the box 29 and is secured thereto by means of a suitable thumb screw 35. The outer extremity of this guide rod 34 is `formed into a claw 36 within which the cov# ered wire is passed preparatory to winding upon the spool 14, the function of this guide rod and the adjustment of the parts carried and controlled by the lever 18 being hereafter more fully referred to.

The head 32 is capable of a rotary movement since the pin 31 lits loosely within the post 30, while the cross pin 33'is likewise capable of a rotary movement in a plane at right angles to the movement of said head, and also the latter can beelevated and low ered and will be guided in its movements by the engagement of said pin and socket, so that it will be clear that the rear extremity of the guide rod 34has a universal pivotal connection.

37 is a pulley carried by the'spindle 12 and connected with the pulley 5 by means of a slack or loose belt 38, the size of the pulley 37 being considerably smaller than that of the pulley 5 for the purpose presently to.

be explained.

39 is a hollow shaft which is vjournaled in horizontal disposition within the frame of the machine and carries at its iiter end the winding drum 40 while its inner Aextremity carries a Worm 41 which is in mesh with thel worm wheel 4. Thesize of this worm 41 is predetermined with respect to"the"f size of the worm wheel 4 so that the number of revolutions per minute of the winding drum is accurately known with respect to the corre sponding number of revolutions of wheel 4. The worm wheel 4, bei on the same shaft with the i I termines the amount of wire .recon d paid out by suchfeed disk, and should 75j. such amount be greater or less according te the number of strands of yarn u ed l n :Ulti elle, size of the wire, feed disks of different diameters are substituted on the platform 6, but in all instances, as above set 'f'r)ii'tli,"t;`ileA relative number of revolutions per minute of the winding drum and the feed disk are predetermined and fixed.

42 is the spool of uncovered wire which is mounted. over a'spindle 43 and rests upon a platform 44 that is supported on ball bearings (shown in dotted lines at Fig. 1) so that the friction which opposes the revolution ofthe spool will be reduced to a ininimum, and the weight of wire carried by lthe spool will therefore be immaterial within reasonable limits. The wire, which it 'will denote by a, is led from this spool threw* a series of arcuately disposed straighten g rolls 45 and thence between the diei-:s of a spring controlled wheel tension 4b through the hollow shaft 39 to the covering device-- This wheel tension is journaled concentric# ally with the are on which the rolls are disposed and the wire is delivered from said tension within the hollow shaft 3G in a straight line which is parallel to the axis of such shaft so that there can be no possible kinking or twisting of the wire at that point. So far as the spring element of said tension is concerned it 1s quite ordinary since it cen.- sists merely in a volute spring b which rests `upon the tension wheel and thumb which is driven against said spring'` 'out `respect to the re'ative arrane ment wheel tension and the straighten' the delivery of the wire from tl the hollow shaft, my lcornbiired stra and tension device is believed to As above stated, 'the covering deT no part of my present invention, onlydeemed necessary to state that the vcop 47 is located within the winding drum -z the usual manner, and that the yarn is passed through suitable tension slots in i] the periphery of the drum and the i l through a guide linger to t nozzle 50 where it is wenn( a which latter passes conce a groove in the nozzle and zr ered with the yarn is'poli A spring controlled polisher el A forward end of the nozzle.

52 is a rod parallel with the shad adjustably secured within a housing ing from thebedgplate 1 b 'yf lneai'is screw 54, and 55 is a headed pin whit disposed. in a general vertical whose lower extremity e through the rod 52 and is ser u eeaeas suitable horizontal adjustment yby means of a set screw 56 driven in the end of this rod lagainst the pin. @n top of the headed por* tion of this pin is loosely j ournaled a disk 57 which is grooved around its periphery as seen at 58, this disk therefore being an idler which is capable of adjustment, by axially adjusting the rod 52, so as to bring one side of said. disk higher than the other or to shift the disk in such manner that it will stand in a horizontal plane, the object of which adjustment will be more particularly referred to later on in this description.

The wire'after it has been covered and which is denoted by Z passes 'around said disk in the groove 58 and then several times encircles the feed disk and is thence led through the claw 36 to the winding spool le, the wire being passed several times around the feed disk in order that the lat-ter may obtain a sulicient grip upon the wire so as to take it up as fast as itis coveredl without any slack and then pay it out to the Winding drum. y

is a bracket which is adjustably .ecured upon the frame of the machine by means of a set screw 60 which is passed through' an elongated slot 6l in the heel of 'the bracket and driven into the4 frame, and 62 .is a spare cop' of yarn whose tube (shown in dotted lines) is detachably secured to the side of. the bracketl o9 by means of a screw 63., this cop being so disposed that the covered wire from the idler 5? directly through the cop tube to` the feed disk, this -agement v ery essential since, when the cop in the ing drum is exhausted,

idler 57 is noved, and this spare cop detached from t he bracket and inserted. in position within the winding drum without breaking the wire. .lifter a fre-sh cop has been thus inserted inthe winding drum the idler is replaced. in position with the wire around. the same.

'lhe horizontal plane of the feed disk may be the same as that of the spinning nozzle, although it different in the present inbut if said nor-)zie and disk are in the same horizontal plane then th idler would be adjusted so that it would liliewise stand. in the same plane, since it is quite essential that there should be no pronounced. angular bending of the wire. But in the present improv it, the feed disk is elevated aoovc -the plane of the spinning nozzle, und therefore the idler has angular adjustnnent4 such as would bring one side down to the horizontal. )lane .of the soinnino nozzle i b whereby the covered wire is delivered. in a straight line and the other side up to the horizontal plane of the feed disk Awhereby such wire is likewise delivered to the feed disk in a straight line.

ln the event that theplane of the feed disk was below that of? the spinning nozzle it Will be obvious that the 'angular adjust' ment'of the idler would'be just'the reverse to that described.

lt is quite necessary that as little opportunity as possible should be given for the breakage of the wire after it leaves the spinning nozzle, and my improvement overcomes all diculties heretofore experienced in this respect, since, by the inward adjustment of the rod v572, the idler may be brought as close as possible to the spinning. nozzle, and this distance between said idler and nozzle may be varied as desired. This near proximity of the idler to the spinning nozzle also reduces, to a minimum the tendency of the Wire to twist or kink while it is being covered. The spare cop is so located on its bracket that it 'will not interfere with the straight draft of the covered wire between the idler and the feed disk, and this is brought about 'by the adjustment of the bracket'as will be clearly understood.

A feed disk large in diameter would of course receive and pay out a greater amount 'of wire at a single revolution than would a disk of smaller diameter, and the size of the feed disk depends upon the number of strands of yarn used in the Winding vopera-.

tion andthe size of the wire, since the 'greater the length of wire covered in a given time by the winding mechanism, the greater will be the length of wire which must be taken up and paid out by the `feed disk. Therefore, l provide feed disks of diilerent sizes, and if it becomes necessary to provide for the feeding of a' greater amount of wire within a given time, I merely replace a feed disk with one of a greater diameter, or, l utilize a smaller feed disk in case a smaller amount of wire is to be taken care of. ln this connection, I would say that` I have accurately determined the various proper sizes of feed disks necessary to provide for the different windings and sizes of Wire now known commercially, but this is a comparatively simple matter owing to the fact that, in my improved machine,

the `number of revolutions per minute of the winding drum with respect to the corre.

sponding number of revolutions of the worin wheel 4 is accurately knownn As hereinbefore stated, the covered wire is paid out from the feed disk through the claw 3G to the winding: spool let which latter .is revolved by mer-.nsV of the slack belt 38,

winding has completely filled the spool, but under none of these conditions, however, is the friction of the belt so great that a breakc-f' the wire would occur. As the wire is wound on the spool, the guide rod 34 will automatically elevated and lowered owing to the vertical reciprocat-ion of the lever 18 by means of the heart cam 17 and the con nections between said lever and tfluide rod5 whereby the wire will be wound around the spool evenly from top to bottom.

ln the event that a tall spool is used, the ohvious adjustments of the rod will be uiade at the outer end of the elongated slot and possibly it may be necessary to ad just the rod 25 as far down within the box 26 as possible, and in making windings around a short spool, the adjustments will he obvious and require no, additional eX- ilanation. 0f course, it- Will be obvious that the threads of `the worm 13 and worm Vwheel may of such character as to effect a more or less rapid revolution of this wheel. wherein-,f the guide rod 3s will be caused to ne moved more or less rapidly between the upper d lower ends of the reel lll, but this a'inatter which dependent on thJ ,gage e covered wire. rlfhe claw 36 holds the F wire to the winding, and the manner in 5C' which the heel end of the guide rod is pivoted permits said rod to be moved in any naue necessary for a neat and proper winding of the wire.
